In order to gain illegitimate access to a network attackers often by-pass access control lists by a) media scavenging b) spoofing c) DOS Pharming?

Attackers often bypass access control lists by using spoofing, which involves disguising their identity or IP address to gain unauthorized access to a network. This technique allows them to impersonate a trusted source, making it easier to exploit vulnerabilities in security measures. Other methods like media scavenging or DOS (Denial of Service) attacks serve different purposes and are not primarily focused on bypassing access controls.
